What is the gallbladder and what does it do?
Bile is synthesized with in liver and drained through Right and Left Hepatic ducts that joins to form Common bile duct (CBD). The gall bladder is a pear-shaped bag that lies under the liver, beneath the rib cage, on the right side of the abdomen that joins the Common bile duct.
The gall bladder stores bile produced by the liver. During meals, especially fatty meals, the gall bladder squeezes out the bile it has stored, into the bile duct.
The bile duct then runs through the pancreas for a bit, and enters the duodenum at ampulla ( also joined by pancreatic duct which drains the digestive juice from the pancreas) where the bile mixes with the food.
